The potentiometer wire is 5 m long and potential difference of 4 V is maintained between the ends. The e.m.f. of the cell which balances against a length of 200 cm of the potentiometer wire is
- A 0.4 V
- B 0.8 V
- C 1.2 V
- D 1.6 V
Answer & Solution
Correct Answer
(D) 1.6 V
Step-by-step Solution
Detailed explanation
\(k = \frac{V}{L}\) \(k = \frac{4 \text{ V}}{5 \text{ m}} = 0.8 \text{ V/m}\)
